Intentional oxygen oscillations on Pd/Al2O3 for enhanced methane removal from the exhaust of natural gas engines

Maneka Claire Roger

Natural gas (NG) is a suitable alternative to gasoline and diesel fuels to decrease the carbon footprint of the mobility and energy sectors. Although NG is considered a fossil fuel, methane (CH4), its main component, can be produced industrially from power ...

Temporary pause in the growth of atmospheric ethane and propane in 2015–2018

Hélène Paule Angot, Ilann Ernest Valentin Bourgeois

Atmospheric non-methane hydrocarbons (NMHCs) play an important role in the formation of secondary organic aerosols and ozone. After a multidecadal global decline in atmospheric mole fractions of ethane and propane – the most abundant atmospheric NMHCs – pr ...

Fault-Tolerant Multi-Level Logic Decoder for Nanoscale Crossbar Memory Arrays

Giovanni De Micheli, Mihai Adrian Ionescu, David Atienza Alonso, Didier Bouvet, Kirsten Emilie Moselund, Yusuf Leblebici

Several technologies with sub-lithographic features are targeting the fabrication of crossbar memories in which the nanowire decoder is playing a major role. In this paper, we suggest a way to reduce the decoder size and keep it defect tolerant by using mu ...
